Mars, What would the issue be with that, other than audio fixes to the radio? We do it sometimes when we have a codeplug from a fleet that adds new radios and I haven't run into an issue, at least that I know of?

Moto makes many undisclosed changes to the XML (codeplug) with each codeplug version. (Codeplug versions are paired with specific firmware versions). When you clone old codeplugs into radios with new firmware/codeplugs, the older codeplug settings (hidden XML data) overwrite current values.
Those values may pertain to audio, trunking configuration, timing, etc. Once you do that, there's no way to fix it unless you have the original (current) codeplug version to dump back in. A "recovery" also fixes it.
Motorola has many issues with their TRBO platform which they have not disclosed to the customers. I have found, confirmed and reported the issues, but the people I report it to no longer acknowledge any communications from me. They are mostly incompetent, incapable, clueless fools who think they know it all. Unfortunately they don't, or I wouldn't be passing along those issues to them, or fixing the audio which they had about 8 years to fix on their own.
Hams who upgrade to the latest firmware, then dump cloned DMR-MARC templates back into their radios', are really just back at square one. And they say stupid shit like "I don't hear any difference". Most hams are kind of green, but it's up to Motorola to ensure certain XML fields are being preserved (not cloned) during the cloning operation.
